Application led April 18, 1904. Serial N0' 203,606.

.To al?, whom, it may concern,.-

Be it known that I, HENRY KLINE, a citizen of the United States, residing at Jackson, county of Jackson, State of Michigan, have invented a certain new and useful Improvement in Artificial Stone Building-Blocks; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings,

y which form a part of this specification.

This invention relates to artificial stone building-blocks.

It has for its object a form of buildingblock adapted for the construction of a wall of the character commonly known as a hollow wall, in which, however, the blocks constituting the inside and the outside courses of the wall are bonded at intervals by parts that are made integral with the blocks and reach across the hollow and are bonded together.

In the drawings, Figure 1 is a perspective of a block embodying this invention. Fig. 2 is a slightly-modified form. Fig. 3 is a sectional elevation across a wall built from the blocks shown in Fig. 1. Fig. 4 is a sectional elevation across a wall built from a block shown in Fig. 2. Fig. 5 is a plan view of a wall as it would appear with blocks of either Fig. 1 or Fig. 2. Fig. 6 shows a corner-block. Fig. 7 shows the end block of an inner wall. This is used in connection with the block of Fig. 6.

The body of the block is a rectangular prismoid and is provided along one side with a projection 2, which may extend as a triangular projection, as shown in Fig. 1, or as a rectangular projection, as shown at 3 in Fig. 2. The width of the projection at right angles to the axis of the main body of the block is of a length nearly equal to the hollow that it is desired to construct between the walls, and at least one surfacethe upper surface of a triangular block and one of the surfaces, either upper or lower, in a rectangular blockis provided with a groove or notch 4, that registers with the corresponding groove in the block that is used to build or construct the inner part of the wall-as, for example, in Fig. 3, where the wall is shown as built of rectangular blocks with'triangular projections. The upper surface of the triangular projection 3b from the block B is provided with a groove 3, that registers with the groove 3e on the lower surface of the triangular projection 3d 'from the block B, and bonding material is used to ll the hollow where the grooves register.

In the form of wall shown in Fig. 3 the two components which comprise the outer and inner parts are bonded together by cross-struts tied together by the bonding material.

In the form shown in Fig. 2 and the Wall built from it (which is shown in Fig. 4) the bonding projection of each piece passes only partially across the space intervening between it and the corresponding block of which the opposite face of the wall is made, and each bonding projection is slightlyless in vertical extension than the body of the block from which it projects. When the blocks of Fig. 2 are assembled in wall form, thereis between the bonding projection of each block and the adjacent face of the opposite block a vertical space, and there is also between the bottom of the projection of one block and the top of the projection from a block in the opposite wall a slight space on the one side, this space being found between those faces of the projections Which are not furnished with the bondinggroove, and those faces which are furnished with the bonding-groove meet.

In neither form of block when assembled in Wall form is there a straight horizontal connection from one face of the wall to the other.

Corner-blocks` like the block C in Fig. 5, are made L-shaped, with a bonding-block 3L at the middle of the long branch of the L-shaped block and a bonding-block 3g at the end of the short section. A block D, (shown in Fig. 7,) with a bonding-'block at the end, is used in the inner wall in connection with the cornerblock.

What I claim is- 1. A rectangular building-block, having a main body part of rectangular prismoidal shape, and a wedge-shaped projection extending from the side thereof and in a direction transverse to the longitudinal axis thereof, the surface forming the base of said wedge-shaped IOO allel to the longitudinal axis of said block, with a similar block having asimilar projection, the two projections engaging, with one lying above the other, substantially as described.

In testimony whereof I sign this specification in the presence oi two witnesses.

HENRY KLINE.
